The kinetic energy of an object is calculated from the velocity and the mass of the object. As you can see from the equation below, the velocity is squared and can have a significant impact on the kinetic energy. Here is the equation for calculating kinetic energy (KE): KE = 1/2 * m * v2. where m = mass and v = velocity.
To calculate kinetic energy, we follow the reasoning outlined above and begin by finding the work done, W , by a force, F , in a simple example. Consider a box of mass m being pushed through a distance d along a surface by a force parallel to that surface.
So the formula for kinetic energy is that it's equal to 1/2 times the mass of the object, times the magnitude of its velocity squared, or another way to think about it, its speed squared. And so given this formula, pause the video and see if you can calculate the kinetic energy for each of these running backs.

The unit of measurement for the amount of energy in the kinetic energy store is the joule (J). Example. A runner with a mass of 60kg is running at a speed of 1 m/s. Calculate the amount of...
An example of rotational kinetic energy would be the earth’s rotation. If an object’s speed and mass is known, you can calculate the kinetic energy. Kinetic energy is measured in a unit called a ‘joule’. Another unit for configuring energy is known as the ‘newton’ (named after Isaac Newton) and is measured through the use of a newton-meter.
